actually he is shy around people he doesn't know but when you get the chance to see him with his friends, he likes to be the center of the attention. He is talking, the others listen. With his friends he is King Juan Carlos!
I looked through all the pictures on this thread. Juan Carlos is such a sweet and nice looking man. I love the pic of Juanqui with David Ferrer. They are wonderful teammates and friends and, as I said, very nice.
